As a clean energy, the development and utilization of solar energy has received more and more attention. Photovoltaic power generation technology uses solar cells to directly convert sunlight energy into electrical energy. It has the advantages of cleanliness, safety, and reliability, and has become one of the important ways to utilize solar energy.

[0003] In recent years, the continuous development of photovoltaic power generation technology and the reduction of costs have made its application scope wider and wider, and has expanded from large-scale ground power stations to distributed photovoltaic power generation systems, such as rooftop photovoltaics, BIPV (building integrated photovoltaics), etc. As an important part of residential buildings, balconies usually have a certain amount of idle space and good lighting conditions, which are very suitable for installing photovoltaic power generation systems and become an ideal place for household distributed photovoltaic power generation.

[0004] However, when the existing photovoltaic brackets are used for balcony photovoltaic, it is difficult to balance performance and cost. Some brackets pursue high performance, such as using complex angle adjustment mechanisms or high-strength materials, resulting in high costs; while some low-cost brackets often have shortcomings in performance, such as low strength, poor stability, and inconvenient installation.

[0005] Therefore, there is an urgent need for a photovoltaic bracket that is easy to install, has adjustable angles, high structural strength, beautiful appearance and moderate cost to meet the growing demand for balcony photovoltaic applications and solve the problem that existing brackets are difficult to balance in terms of performance and cost.

[0008] In order to facilitate disassembly and assembly, the connecting piece is a bolt or a latch.

[0009] In order to adapt to different installation environments, the number of adjustment holes on the second support rod is 3-5.

[0010] A further solution is that the number of the adjustment holes on the second support rod is 4, and the positions of the adjustment holes are arranged so that the second support rod can form any angle of 15 degrees, 25 degrees, 35 degrees, and 45 degrees relative to the first support rod.

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1.

[0025] like Figure 1 As shown, the photovoltaic balcony bracket described in this embodiment includes a photovoltaic back frame 100, a bracket body 200 and a connector 300, wherein the photovoltaic back frame 100 is a standard photovoltaic module back frame for fixing photovoltaic modules, and at least two bracket bodies 200 are spaced apart on the photovoltaic back frame 100 to provide stable support for the photovoltaic back frame 100.

[0026] In a specific implementation, two bracket bodies 200 are provided, wherein each bracket body 200 comprises:

[0027] The first support rod 10, in the present embodiment, is made of aluminum alloy, and is fixedly mounted on the back of the photovoltaic back frame 100 by means of bolts or rivets, etc., to provide the main supporting force for the bracket, and the second support rod 2 is also made of aluminum alloy, and one end of the second support rod 2 is pivotally connected to one end of the first support rod 10 to form an angle-adjustable connection, and the second support rod 20 is provided with a mounting hole 21 for fixing to a building, for example, an expansion bolt can be installed at the mounting hole 21 to fix the second support rod 20 to the balcony wall to achieve a stable installation.

[0028] In addition, a plurality of adjustment holes 22 are arranged at intervals along the length direction on the second support rod 20. The adjustment rod 30 is made of aluminum alloy and has an L-shaped cross section. One end thereof is pivoted through the middle of the first support rod 10, and the other end is selectively pivoted to any adjustment hole 22 on the second support rod 20 through a connecting member 300. That is, by selecting different adjustment holes 22, the angle of the second support rod 20 relative to the first support rod 10 can be adjusted, thereby adjusting the inclination angle of the photovoltaic module so that it can obtain the best angle of sunlight exposure and improve power generation efficiency. In this embodiment, if Figure 3 As shown, the connecting member 300 may be a bolt or a latch. In a specific implementation, a bolt is preferably used to better fix the connection between the adjusting rod 30 and the second support rod 20 after the tilt angle is selected.

[0029] In this embodiment, the cross-sections of the first cross bar 10 and the second cross bar 20 are both L-shaped. The L-shaped cross-section requires less material than other cross-sections (such as round or square) under the same strength requirement, which can reduce the overall weight of the bracket, facilitate transportation and installation, and is low-cost.

[0030] In another example, if Figure 4 As shown, the pivot connection between the second support rod 20 and the first support rod 10 can also be achieved through the connecting member 300, which helps to reduce the types of assembly parts, further simplify the support structure, and reduce manufacturing costs.

[0031] In some embodiments, the number of adjustment holes 22 on the second support rod 20 is 3-5. By providing multiple adjustment holes 22, the user can select different hole positions to connect the adjustment rod 30 according to the actual installation environment and lighting conditions. The number of 3-5 adjustment holes 22 can meet the needs of most users.

[0032] Specifically, if Figure 2 As shown, the number of the adjustment holes 22 on the second support rod 20 is 4, and the positions of the adjustment holes 22 are arranged so that the second support rod 20 can form any angle of 15 degrees, 25 degrees, 35 degrees, and 45 degrees relative to the first support rod 10.

[0033] In this way, the positions of the four adjustment holes 22 are set so that the second support rod 20 can form four commonly used tilt angles of 15 degrees, 25 degrees, 35 degrees, and 45 degrees relative to the first support rod 10. Users can select appropriate adjustment holes 22 according to seasonal changes and easily adjust the tilt angle of the photovoltaic module to always maintain the best light receiving state, thereby improving power generation efficiency. In addition, if the user's balcony is not facing due south, or there are obstructions such as buildings or trees around, the problem of insufficient light can be compensated by adjusting the tilt angle of the photovoltaic module to further improve power generation efficiency.

[0034] In another example, during the actual installation between the first support rod 10 and the second support rod 20, the assembly of the adjustment rod 30 can be cancelled to show that the second support rod 20 forms a tilt angle of 0 degree relative to the first support rod 10. Assuming that the user's balcony railing is high and unobstructed, in this case, the user can install the photovoltaic module vertically on the balcony so that it can obtain the best angle of sunlight exposure without adjusting the angle. Therefore, the user can selectively cancel the assembly of the adjustment rod 30 and directly connect the first support rod 10 and the second support rod 20 to form a tilt angle of 0 degree without affecting the power generation efficiency of the photovoltaic module.

[0035] In some embodiments, Figure 1 and Figure 4As shown, the first support rod 10 and the second support rod 20 are pivotally connected to each other at one end and at both ends of the adjustment rod 30, and each of the connection ears 400 is provided with a through hole, and the connection member 300 passes through the through hole to connect the first support rod 10, the second support rod 20 and the adjustment rod 30 to each other. Specifically, each connection ear 400 is provided with a through hole, and the connection member 300 (such as a bolt) passes through the through hole on the connection ear 400 to connect the first support rod 10, the second support rod 20 and the adjustment rod 30 to each other to form a stable triangular structure, and the connection ear 400 can also make the ends of the rods (10, 20, 30) more rounded, avoid sharp edges and corners, improve the safety of the bracket, and prevent users from being accidentally injured during installation or use. For example, in some embodiments, the connection ear 400 can be designed to be circular or elliptical, and the through hole can be set at the center of the connection ear 400, so that the ends of the rods can be smoother and potential safety hazards can be reduced.

[0036] In some embodiments, Figure 1 As shown, a hook 23 is fixedly mounted on one end of the second support rod 20 pivotally connected to the first support rod 10, and the opening of the hook 23 faces the position where the adjustment rod 30 is pivotally connected to the second support rod 20. With this structural design, the user can choose a suitable installation method according to the actual situation and the type of balcony railing. For example, if the user's balcony railing has a special shape, such as a round railing, or the user does not want to drill holes on the wall or railing, the user can choose to directly hang the hook 23 on the second support rod 20 on the balcony railing to complete the installation, without using the installation hole 21 and fixing parts such as expansion bolts, and without drilling holes on the wall or railing.

[0037] In some embodiments, the exterior surfaces of the photovoltaic back frame 100, the bracket body 200 and the connector 300 are coated with a black coating. Specifically, the black coating can effectively absorb light, reduce light reflection, especially reduce the reflection of sunlight, thereby reducing light pollution, and further improving the visual environment, making the photovoltaic bracket more coordinated with the surrounding environment.

[0038] In some embodiments, Figure 1 As shown, a cross bar 500 is also included, and both ends of the cross bar 500 are respectively fixedly connected to the two second support rods 20. The existence of the cross bar 500 will not affect the angle adjustment function of the bracket, and the user can still adjust the tilt angle of the photovoltaic module through the adjustment rod 30 and the adjustment hole 22. The cross bar 500 connects the two second support rods 20 to form a stable frame structure, which can effectively enhance the overall strength and stability of the bracket, so that it can withstand greater external forces such as wind and snow loads, and has higher reliability and safety.

[0039] In another example, the two adjustment rods 30 may also be connected by a cross bar 500 to form a more stable frame structure, which can effectively ensure the strength and stability of the bracket even when supporting photovoltaic modules with larger sizes.

[0040] In some embodiments, the structure of the first brace 10 is the same as that of the second brace 20. In this way, on the one hand, only one set of molds and tooling is needed to manufacture the brace, and there is no need to design and manufacture molds and tooling for two braces of different structures respectively, which can significantly reduce the manufacturing cost and maintenance cost of the molds and tooling, thereby reducing the overall manufacturing cost of the product. On the other hand, it can also reduce the types of inventory, reduce the difficulty and cost of inventory management, such as reducing the demand for storage space, simplifying the inventory counting process, etc., and in actual assembly, the same brace can be used interchangeably, and there is no need to distinguish the installation positions of the first brace 10 and the second brace 20, thereby improving assembly efficiency.

[0041] The photovoltaic balcony bracket provided in this embodiment has the advantages of easy installation, adjustable angle, high structural strength, beautiful appearance, moderate cost, environmental protection and energy saving. It can effectively solve the shortcomings of balcony photovoltaic bracket technology in related technologies and meet the growing demand for balcony photovoltaic applications. It has good promotion and application value.
